That's why we use a CM500

What matters is smooth (flat) response from about 200 Hz to about 3 kHz as heard at the ear of the operator. The laws of physics dictate that uniformity of high frequency response is limited by diaphragm size -- the larger the speaker, the worse it sounds off axis. The speaker built into the K3 is a nice small one, so it has pretty good off axis response, but it faces straight up. In most shacks, the highs bounce off of nearby surfaces to get to the listener. A front-facing loudspeaker will have flatter response, but takes up more space on the operating desk.
